Hey guys, have had my r33 gts-t for 4 months with zero problems until this morn...

This morn i drove back from my nightshift and parked at the side of the house.

Left the car for 6 hrs.

This arvo jumped in to start the car and it wont.

It is cranking fine but wont start

I tried to cable jump start it but it just cranked even faster with no start.

My air con is screwed and makes a noise as I turn the key to accessories so Im unable to confirm if fuel pump is priming (althought i think i can hear it)

What should i try before calling NRMA and wasting money???? :S

Where abouts is the fuel pump located? im going to try hitting it while my cousin cranks.

Thanks alot in advance fellas

Ryan

From my experience, its usually a crank angle sensor or a bad ecu that causes this when the obvious has been ruled out.

But first thing is first. You should verify you are getting optimum fuel pressure when cranking, fit a fuel pressure gauge or if you cbf unplug one of the fuel hoses after the fuel filter and see if yours squirts out when you prime it.

Also make sure none of the earth points on your car are rusted or loose.

If you turn your key slowly from 'ON' to 'Start' you will start priming the fuel pump about halfway towards start. It's easier to hear on my car cause I have an aftermarket fuel pump, but it should work if you slowly turn it till you hear the fuel pump prime then stop and hold it and it will continue priming

Unless my car is just weird :)

How long did you crank the car for? Mine sometimes randomly takes about 10 seconds of solid cranking to start for some reason. But its only once every so often and its fine before and after this

Just remember do not crank for more then 20seconds at a time and allow a good amount of time between long cranks to let the starter cool

      They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.

      Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.
